FAIL-SAFE TIMER VALUE – BIT 0 (LSB)
FAIL-SAFE TIMER VALUE: Write to this register to set the value for the fail-safe
timer. The default value is 8400h. The timer has a 30ns resolution (PCI clock).
The timer is loaded when an access is initiated on the local bus and counts down
until the access is completed. It will time out if it reaches 0. For test purposes,
the failsafe timer can be loaded and decremented via failsafe timer load write
and decrement operations generated through REG7.
